Outline of Final Research Achievements

In order to reduce the transmission loss of the micro- and millimeter-wave power in the long-distance transmission line, we developed a real-time profile and position monitor of Mega-Watt millimeter-waves in evacuated corrugated waveguides, and demonstrated a possibility of measuring the power profile of Mega-Watt level millimeter-waves for real-time. The system can be controlled and the profile data also can be acquired remotely. The measured profile data using Mega-Watt and sub-second pulse power from a 154GHz gyrotron well agreed with the burn-pattern obtained using thermal-paper in the short pulse (several milli-seconds) gyrotron operation. Additionally, the power linearity of the analyzed monitor signal was also confirmed in the several power levels. The analyzing method of the included mode contents is also proposed.
